The singer was all smiles as she was snapped wearing a black figure-hugging number with a super-plunging cut-out neckline, which was showing off her major cleavage (and some, er, pretty necklaces).

Nic teamed the hot, revealing look with a black clutch, black heels and a loose and wavy mane.

Hours before, the sexy singer tried her hand at an udder new skill, as she milked a goat live on radio (yes, seriously). But she was promoting the music, so it was needed, of course.

Nicole was set the challenge during the Capital Breakfast show by presenters Dave Berry and Lisa Snowdon and she squealed as she got to grips with Betty the goat. We would have loved to have seen this.

As she started the task, Nicole said: "It's so weird. I've never milked anything before. Wow, this is fascinating. Oh my goodness there's so much milk coming out. It's so soft and gooey." (Stop your mind from racing, please, for one second).

Explaining the technique to listeners, Nicole said: "Put it in your hand, then let it fill up with milk, and then you have to just gently squeeze and pull."

The stunt tied in with the programme's regular on-air theme of its "butt stick" invention - butter in the form of a stick. It sounds intriguing.

She told listeners: "I'm gonna be doing the music, touring and stuff, so getting that our there!”

Asked if she had a prediction as to which judge would have a winning act this year out of Cheryl Cole, Mel B, Simon Cowell and Louis Walsh, she said: “Oh my gosh - it's too early! I don't even know who's competing!

Dave pushed her on the topic and asked: “Who would you like to see win?” She replied: “Louis! He did win once, out of the ten years!” Bless him.
